Apparatus and method of manufacturing expanded sheet metal

摘要

An apparatus and method for creating expanded and non-expanded regions on a sheet of sheet metal. The apparatus includes a programmable controller, a sheet metal feeder for incrementally advancing the sheet metal, and a cutter/expander for generating rows of expanded metal apertures. The controller selectively controls both the amount of incremental advance provided to the sheet metal by the feeder and the timing and location of the cutting and expanding provided by the cutter/expander; the combination of which creates such regions.
